Heart beat frequency spectrum mapping auscultation device and using method thereof

Abstract

The invention discloses a heart beat frequency spectrum mapping auscultation device and a using method thereof. The using method comprises the following steps: continuously detecting the position of a specific detection point of the ventricular wall or the vascular wall through transmitting-receiving of ultrasonic waves and rear-end geometric inversion in an auscultation head, so as to obtain a point beat wave; mapping the point beat wave to the human ear hearing sensitive area by using a signal processing method, converting electrical signals into sound signals through an electro-acoustic converter, and playing the sound signals. The heart beat frequency spectrum mapping auscultation device comprises the flexible auscultation head, a processing module and the electro-acoustic converter, wherein the bending degree of the flexible auscultation head is adjusted according to the requirements of the detection parts; a coupling agent is clung to the body surface of a specific auscultation part to be used for transmitting and receiving ultrasonic waves and carrying out data communication; the parameter setting, data communication, point beat wave inversion, signal processing and man-machine interaction of the whole device can be realized by the processing module; the digital-to-analog conversion, electro-acoustic conversion and sound playing can be realized by the electro-acoustic converter. The device has the advantages of being high in detection precision, clear in sound and the like, thereby being suitable for auscultation of heat vessels, lung, abdomen and other organs.

Description

Technical field [0001] The present invention mainly relates to the technical field of auscultation, in particular to a method and device for using a heart pulse frequency spectrum mapping auscultation device. Background technique [0002] Medical examinations often use inspection, palpation, auscultation and necessary B-ultrasound, electrocardiogram and other detection methods. Among them, auscultation is to use a stethoscope to amplify the sound of organ activities and block environmental noise. Doctors diagnose the pathological changes of related organs according to the characteristics of the sound and its changes. It is widely used in the detection of the heart, lungs, and abdomen. Among them, the heart sound refers to the sound produced by the vibration caused by the contraction of the heart muscle, the closing of the heart valve and the blood hitting the wall of the ventricle and the wall of the aorta. Doctors can directly hear heart sounds and mixed murmurs in the chest wi...
